EXAMPLES = '''
Start one docker container running tomcat in each host of the web group and bind tomcat's listening port to 8080
on the host:
Build docker image if required. Path should contains Dockerfile to build image:
- hosts: web
sudo: yes
tasks:
- name: check or build image
docker_image: path="/path/to/build/dir" name="my/app" state=present
Build new version of image:
- hosts: web
sudo: yes
tasks:
- name: check or build image
docker_image: path="/path/to/build/dir" name="my/app" state=build
Remove image from local docker storage:
- hosts: web
sudo: yes
tasks:
- name: run tomcat servers
docker: image=centos command="service tomcat6 start" ports=:8080
docker_image: name="my/app" state=absent
The tomcat server's port is NAT'ed to a dynamic port on the host, but you can determine which port the server was
mapped to using docker_containers:
- hosts: web
sudo: yes
tasks:
- name: run tomcat servers
docker: image=centos command="service tomcat6 start" ports=8080 count=5
- name: Display IP address and port mappings for containers
debug: msg={{inventory_hostname}}:{{item.NetworkSettings.Ports['8080/tcp'][0].HostPort}}
with_items: docker_containers
Just as in the previous example, but iterates over the list of docker containers with a sequence:
- hosts: web
sudo: yes
vars:
start_containers_count: 5
tasks:
- name: run tomcat servers
docker: image=centos command="service tomcat6 start" ports=8080 count={{start_containers_count}}
- name: Display IP address and port mappings for containers
debug: msg={{inventory_hostname}}:{{docker_containers[{{item}}].NetworkSettings.Ports['8080/tcp'][0].HostPort}}"
with_sequence: start=0 end={{start_containers_count - 1}}
Stop, remove all of the running tomcat containers and list the exit code from the stopped containers:
- hosts: web
sudo: yes
tasks:
- name: stop tomcat servers
docker: image=centos command="service tomcat6 start" state=absent
- name: Display return codes from stopped containers
debug: msg="Returned {{inventory_hostname}}:{{item}}"
with_items: docker_containers
